How do you know when it’s real love?

Not for your own relationship. (That’s a question for another column.) But as an outsider looking at a couple, is it possible to discern real love just by looking at how they interact?

For some, it was evident in the way Travis Kelce of the Kansas City Chiefs let out a joyous groan as he pulled Taylor Swift into a tight hug and kiss after his team won the A.F.C. championship over the Baltimore Ravens on Sunday to reach the Super Bowl.

For others, it was clear the couple were head over heels after the pop star was seen in another clip stretching her bright red lips from ear to ear as she excitedly congratulated her boyfriend in a dense crowd of people. Amateur lip readers shared transcripts of the couple’s mostly inaudible conversation. “I love yous” were reportedly exchanged.

For Venus Cuffs, a nightlife producer and former dominatrix, the couple’s love is undeniable.

“I think it’s a real relationship, even if people think it started off as some kind of P.R. relationship,” Ms. Cuffs said on Wednesday. “I think they have genuine feelings for each other.

The reason for her confidence? “You can tell by body language,” Ms. Cuffs said. “The way they look at each other, their eye contact, the way he touches her back — just small gestures like that.”

With the help of several camera angles and differing video compilation, fans have been analyzing the pair’s body language, many of them admitting to watching it repeatedly — some out of admiration, others skepticism. Aside from the political conspiracy theories coming out of the Make America Great Again camp, there are others who simply aren’t convinced by the couple’s public displays of affection.
